Very Interesting

Givens:

1, The ratio of male/female beween 15 and 64 years = 1.06;

2, The ratio of life span of female/male = 77.11/72.82 = 1.06

Thus,

the ratio of the total life span of all femals/all males = 1.06 /1.06 =1.

Globally, the total life span of all females = the total life span of all males.
